Abstract: 713,555. Weight assisted driving mechanism. MICHALITSIANOS, E. M. Nov. 20, 1952 [Nov. 26, 1951], No. 27634/51. Class 10 Weight assisted driving mechanism comprises a rotatable driving member supporting thereon in angularly spaced relation a plurality of weighted members movable from a first position close to the periphery of the driving member to a second position extending outwardly therefrom power operated means being provided to successively move each of said weighted members from its first to its second position whereby the driving member is rotated by the out of balance turning moment corresponding to the resultant of the several individual turning moments of the weighted members. In the embodiment shown the driving member in the form of a flywheel 8 is secured by means of angle.straps 9 to the rotatable annulus 1 of a pump of the type disclosed in Specification 697,397, [Group XXVIII], weights 13 being attached to the periphery of the wheel 8 by U-shaped brackets 11 and arms 12. Each weight is provided with a lug 14 which accommodates a pin 15 such that diametrically opposed weights may be connected by a strap 16. A motor driven belt mechanism consisting of motor 19, pulley 21, belt 18 and hook members 23 is provided to ensure that each weighted member is in its extended position when at the point B. This is effected by the hook 23 on the belt engaging the pin 15 of a weighted member at the point A. As shown in Figs. 3, 4, the arm 12 is connected to the bracket 11 by a nut and bolt 25 the cross-section of part of the bolt being square such that a cam 29 may be fitted and held against rotation. This cam is-spring (30) loaded against the lower cam surfaced face 28 of the arm 12 so that when the weight is caused to fold up as at D it is releasably held in position so counteracting the effect of centrifugal force on the folded weight. The arm 12 is provided with a pin 27 which, engages shoulders 26 cut into one of the arms of the bracket 11 thereby limiting the angular movement of the arm from the folded to the extended positions. In a modification the weighted members comprise discs pivoted direct to the driving member the latter being mounted on a shaft having belt pulley and flywheel means for transmitting the drive to the machine.

Patent GB-664376-A (GB)
Title: Improvements in or relating to the continuous crystallisation of solids from their solutions
IPC: B01D9/00
Filed: 1948-11-03
Abstract: In the crystallization of solids from solutions wherein the solution is passed continuously into the top of a vertically-disposed cylindrical vessel, provided with a closely-fitting stirrer and a jacket through which cooling liquid is circulated in counter-current with the flow of solution, while a suspension of crystals in cooled solution is continuously discharged from the bottom of the vessel; the average temperature-difference between the solution and the cooling liquid and the speed of the stirrer are adjusted so that more seed crystals are formed per unit of time than developed crystals are discharged, the excess of seed crystals being dissolved in the warmer parts of the solution as a result of the stirring.  The process enables a coarse crystalline product to be obtained with high rate of output.  Several crystallizing vessels may be connected in series. In an example, 500 kg. per hour of hot anthrocene oil is passed into the top of a cylindical crystallizer, 2 metres high and 1 metre in diameter, provided with a helicoidal stirrer and scraper making 20 revolutions per minute, and with a jacket corresponding to a cooling-surface of 4.1 m2.  Water is passed into the bottom of the jacket at 17 DEG  and leaves the top at 34 DEG C.  The average temperature of the oil in the crystallizer is 45 DEG C.  The suspension of anthracene crystals in oil discharged at the bottom of the crystallizer is passed to the top of a second and similar crystallizer.  Cooling water enters the jacket of the second crystallizer at 13 DEG  and leaves at 17 DEG C.  The suspension of crystals discharged from the bottom of the second crystallizer is passed to a storage vessel provided with a stirrer, and is then conducted to a centrifuge. The product from the centrifuge was coarse-grained (greater than 0.25 mm.) and contained 20 per cent of pure anthracene.  A second example describes the crystallization of calcium nitrate tetrahydrate from a nitric acid solution of raw phosphate.  The method may also be applied to the crystallization of naphthalene from crude naphthalene oil, to the recrystallization of crude anthracene from centrifuged naphthalene oil, and to the separation of ammonium chloride and of potassium ferrocyanide from their aqueous solutions.  Specifications 260,133, 260,691, 261,085, [all in Class 32], and 559,992 are referred to.

Title: Method and apparatus for the control of a weight suspended from a floating vessel
IPC: F15B21/08
Filed: 1974-06-27
Abstract: 1485503 Well drilling VETCO OFFSHORE INDUSTRIES INC 27 June 1974 [27 June 1973] 28592/74 Heading E1F A drilling vessel supports a drill string via a hydraulic piston and cylinder unit communicating with a pneumatic-hydraulic accumulator in which the volume of liquid is maintained constant, in spite of relative movement of the piston and cylinder as caused by wave action &c, so that the pressure in the cylinder and consequently the weight on the bit remains constant, liquid being transferred between the accumulator and a reservoir automatically to maintain a constant volume thereof in the accumulator. In the system shown, the cylinder 4 carries a split travelling block 5 and the piston 8 supports the kelly 12 via a tubular rod 9 receiving a piston 13 on a rod 17 depending from the cylinder head. There are thus two concentric annular pressure chambers in the cylinder, the outer chamber communicating direct with accumulator 30 while the inner chamber 18 communicates with accumulator 30a and with port 57 of a 3-way valve 20 operable to connect port 57 to either of ports 60, 62. A reference pressure established by accumulator 34 is sensed by transducer 36, the pressures in the two annular chambers are sensed by transducers 40, 41 and the load on hook 10 is sensed by transducer 35, these transducers supplying electrical signals e 1 -e 4  respectively to comparators 42-45 (Fig. 3) of which comparators 42, 43 control switches 65-68. When the vessel is rising and liquid tends to be displaced back into the accumulator 30, the consequent pressure rise causes signals e 2 , e 3  to exceed e., whereby switches 65, 68 are closed and valves 23, 25 opened so that liquid from the accumulator 30 can pass to reservoir 21, the valve 20 at this stage having its ports 57, 60 interconnected. When the vessel is falling and liquid tends to be drawn from the accumulator, the consequent pressure drop causes signals e 2 , e 3  to fall below e 1 , whereby switches 66, 67 are closed and valve 22 is opened so that liquid is supplied to accumulator 30 by pump 24 or accumulator 24', the valve 20 having its ports 57, 62 interconnected at this stage. Valve 20 is of the type including a relay spool and a pilot flapper controlled by opposed coils. Instead of operating valve 20 in a bang-bang mode via switches 65, 66, it may be controlled by a differential amplifier 45a so as to meter addition of fluid to or its removal from the accumulator system at a rate proportional to the difference between e 1  and e 2
